V MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 281,939, dated July24-, 1883. Application filed June '7, 1883. (No model.)

To all whom it may concern:

Be it known that I, O; F. STEDMAN, of Fre. donia, in the county ofChautauqua and State of New York, have invented certain new andusefulImprovementsinMechanicalllfovements for Operating Ohurns and\Vashing-lVIachines;

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use it, reference being hadto theaccompanying drawings, which form part of this specification.

My invention relates to an improvement in mechanical movements foroperating churns and washing-machines; and it consists, first,inaweighted swinging pendant which has connected to its upper end an armwhich is provided with means of attachment for the dasher of a clmrn orthe pounder of a washing-machine; second, in the combination of theswing ing pendant, the frame in which it is pivoted, and an adjustableframe having springs at tached thereto for regulating the movement ofthe pendant; third, in the combination of a weighted swinging pendant,having an arm attached to its upper end, with a suitable spring, arm, orcatch, which is secured upon the upper side of the frame, for holdingthe dasher of a churn or the pounder of a washing-machine, all of whichwill be more fully described hereinafter.

The object of any invention is to provide a mechanical movement which isespecially adapted to be used where a reciprocating movement isrequired, as in churns and pounder washinganachines, and which is soconstructed that it can be operated rapidly and easily.

Figurel is a vertical longitudinal section of a machine embodyingmyinvention. Fig. 2 is a plan viewof the same. Fig. 3is a rear view.

Arepresents the stand or frame upon which the tub or churn is to beplaced. Rising upward from one end of this frame are the two standardsB, between the upper ends of which is pivoted the swinging pendant orframe 0. This frame is secured by means of setscrews D and short rods orjournals E, which pass outward through the upper ends of the frame C,washers F, and the upper ends of the standards B. Short hearings orjournals are used, as here shown, for the purpose of allowing theswinging frame or pendant G to be removed from between the standards Bwhenever it is desired.

Pivoted to the upper ends of the two standards B, and reaching acrosstheir tops, is the holding-band or cross-piece G, which braces thestandards together. Vhen it is desired to remove the swinging frame 0,it is only necessary to remove the set-screws and then force the shortbearings or pivots inward, when the frame can be readily removed. To theupper end of this swinging frame or pendant O is rigidly secured the armH, which projects outward any suitable distance, and which has a slot,1, cut in its outer end, to allow the churndasher or clothes-pounder tobe inserted therein. In order to connect this churn-dasher orclothes-pounder directly to the arm, there is secured upon its top aspring holding device, J, which consists of two spring-prongs, which areforced apart as the dasher or pounderrod is forced in between them.After the rod has been forced in between them they spring back and holdit, so that there is no danger of its be coming displaced.

Secured to the lower end of the swinging frame or pendant C is theweight L, which weight is secured to the frame or pendantGin such amanner as to project as far beyond it as possible in an outwarddirection. The manner of attaching the weight L to the pendants causesthe pendants to swing inward,and thus cause the arm H to assume an angleupward. By means of this construction a much greater upward stroke isobtained. This weight, attached to the lower end of the swingingpendants, gives them a momentum, so as to cause them to vibrate back andforth, having once been started in motion, and thus make it much easierfor the operator to keep them in motion. The weight also enables aharder stroke to be given with less exertion to the operator, who

' keeps the pendant 'in motion by means of the handle P.

In order to regulate the movement of the pendant and prevent itsmovement from jarring the standards, there is attached to the standardsthe two supports 0 for the springs Q. These supports have their endsbent at right angles, as shown, so as to catch over the outer or innersides of the standards, and each of these ends is made slotted, asshown, so that these supports can be adjusted back and forth, for thepurpose of bringing the coiled springs nearer to or farther from theswinging frame or pendant. The springs Q are secured to these supportsjust opposite the center of the pendants or frames, and as the pendantswings back and forth it alternately strikes the springs, compressesthem, and then the recoil of the spring throws the pendant in theopposite direction. In this manner the motion, after it has been oncestarted, can be readily and easily kept up for a much longer time thancould be done were the springs not used. By adj usting thespring-supports, the length the weight- 2. The combination ofthe frameA, the stand ards B, the swinging pendants 0, having the arm H attachedto their upper ends, and the weight L attached to their lower ends, theweight L being attached to the standards so as to project outward beyondthem as far as pos sible, substantially as described.

3. The combination of the weighted swinging pendants, having the arm Hattached to their upper ends, with the spring-catch J, which is securedupon the top of the arm, substantially as specified.

4. The combination of the standards, the weighted swinging pendants,having the arm H attached thereto, the spring-supports, and the springs,substantially as shown.

5. The combination of the frame A, the stand ards B, the swingingpendants, having a weight attached to their lower end, and the arm H totheir-upper one, the spring-supports, and the springs, substantially asset forth.

Intestimony whereof I affix my signature in presence of two witnesses.

O. F. STEDMAN.
